Question 1 of 5
A nurse is caring for a client who has thrombophlebitis and is receiving heparin by continuous IV infusion. The client asks the nurse how long it will take for the heparin to dissolve the clot. Which of the following responses should the nurse give?
Correct Answer: D
Rationale: The correct answer is D: Heparin does not dissolve clots. It stops new clots from forming. Heparin is an anticoagulant medication that works by inhibiting the formation of blood clots, not by directly dissolving existing clots. This action helps prevent the clot from getting bigger and reduces the risk of new clots forming.
Therefore, it is essential for the nurse to educate the client that heparin does not dissolve the existing clot but rather prevents further clot formation.
Choice A is incorrect as oral medications typically do not directly dissolve clots, and the statement is misleading.
Choice B is incorrect as pharmacists are not typically responsible for providing information on the mechanism of action of medications.
Choice C is incorrect as the time it takes for heparin to reach therapeutic levels is not directly related to clot dissolution.
